Research Study Shows Extensive Damage Caused by Common Teeth-Whitening Products

Credit: Getty ImagesResearch led by scientists at the University of Toronto highlights the considerable damages that can be triggered by common teeth-whitening agents.Published just recently in Nature Scientific Reports, the study assessed the dental cell damage caused by carbamide peroxide teeth-whitening remedies.It found that a suggested application of only 10 percent carbamide peroxide gel...

Selfies From Before Their Disappearance Can Help Future Forensic Dental Identification

Via Tyngsboro Cosmetic DentistrySelfies taken before a person's disappearance can indeed provide valuable information for forensic dental identification. Dental records play a crucial role in identifying individuals when other forms of identification may be unavailable or inconclusive. Selfies that capture clear images of a person's smile, teeth, and dental structures can assist forensic experts...

How do Cells Obtain Their Shapes? A new Mechanism Determined

One of the research projects being carried out by the experimental biologists in the Martin Laboratory at the University of Lausanne, under the direction of professor Sophie Martin, involves using light to trigger processes within genetically modified fission yeast cells. When team members were carrying out these experiments, they noticed that a certain protein...

‘Frameshifting’ Therapy for Pole Cell Cancers Minimizes Size and the Spread

New Frameshifting Therapy Effective Against Mast Cell CancersA team of researchers at North Carolina State University has developed a new frameshifting therapy that has shown promising results against mast cell cancers in mice. Mast cell cancers are a type of cancer that affects the immune system and can be difficult to treat. In the...

Regenerative Dentistry Discovery: Biological Therapy for Damaged Teeth

Via SmilesDrs.comRegenerative Dentistry BreakthroughResearchers at King's College London have developed a biological therapy that could revolutionize the way damaged teeth are treated. The therapy, which involves the use of a small molecule drug called Tideglusib, has been shown to stimulate the stem cells inside teeth, encouraging them to regenerate damaged tissue.Tooth decay and trauma...

Physicists Develop an Unusual ‘Wigner Crystal’ Made Simply of Electrons

In 1934, Eugene Wigner, a pioneer of quantum mechanics, theorized of an odd sort of matter-- a crystal made from electrons. The idea was very straightforward, proving it had not been. With limited success, physicists tried many tricks over eighty years to nudge electrons right into forming these so-called Wigner crystals. However, in June,...

The Research Team Discovers That it Takes Some Warmth to Form Ice on Graphene

In a paper released in Nature Communications, the research study team describes the complicated physical processes working to recognize the chemistry of ice formation. The molecular-level viewpoint of this process may assist in forecasting the formation and melting of ice, from singular crystals to glaciers and ice sheets. The latter is essential to measure...
